Of course with 3-4 weeks distance.
No, you do not have. The complete vaccination protection is reached 2 to 3 weeks after the 2nd vaccine, another vaccination in the 3 to 4 weeks distance will not be brought on. However, a refresh vaccination after half a year to a year can be useful.
No No and again Neeinn. Your body produces a lot of antibodies, which is needed and vaccinating 10 times in a row, does not have an advantage.

No, you do not have that too. And no, there is no study.
No, you do not have that.
